Satisfying Block Shredder Machine | Closed Loop Particle Factory 4K

A closed-loop shredding machine, simulated particle by particle. Colour blocks drop into a twin-drum shredder. The teeth draw each block in and tear it into thousands of particles, which run down a tube into the chamber, where a slow three-arm agitator folds them into a rainbow. A metered spout in the chamber floor feeds a return belt, a bucket elevator throws the material back to the top, and the feed belt carries it into the shredder again. Nothing leaves the machine. The blocks arrive faster and faster, the spout never opens wider, and by the end the chamber is packed and the shredder is choking on its own returned material. Every particle is simulated against real machinery — belts, cleats, shredder teeth, agitator paddles. 78,000 of them by the end. Rendered 4K60. #usa
